SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 539,140, dated May 14,1895. Application filed July 21, 1893. Serial No. 481,092. (to model.)

' To all whom it may concern:

'Be it known that I, ISAAC W. LORD, a citizen of the United States,residing at Oucamonga, in thecounty of San Bernardino and.

State of California, have invented a new and useful Improvement inSash-Fasteners, of which the following is a specification.

My invention relates more especially to those fasteners which areadapted for use on car windows and other sliding sash. It is alsoapplicable to sliding doors and other analogous uses.

Heretofore with such devices in order to apply them to the sash it hasbeen necessary to cut away the sash to receive the crank shaft, and toprovide in addition a fastening plate whereby to pivot the crank shaft,which must be rotated to operate the catch.

The object of my invention is to provide a catch which may be applied tosashes without cutting away the sash to receive the crankshaft, and toso arrange the parts that the only opening in the face of the sash willbe one communicating with the passage for the rod which operates thesash and this opening will be covered and hidden from view by the devicewhich operates as the crank-shaft, so that a single screw will securethe crank-shaft in position, so that it will hide all disfigurement.

A further object of my invention is to providea device which will bevery cheap, ornamental and effective in use and of such simplicity thatit will be very easy tovapply and not liable to get out of order.

My invention comprises the peculiar arran gements of parts whereby Iaccomplish the objects specified.

My improved sash catch is provided with a revoluble crank plate, adaptedto be secured to the face of the sash frame by means of a centrallyarranged pivot passing through the plate and into the sash, such platebeing provided on one side with a projecting pin arranged to engage thebolt operating rod, and provided on its other side with an outwardlyprojecting handle.

My invention comprises the combinations and arrangement of partshereinafter fully set forth and claimed.

The accompanying drawings illustrate my invention.

Figure 1 is a fragmental view of the lower portion of a sash providedwith my invention and mounted in place in a casing, fragments of whichare shown. Fig. 2 is a mid-section of the same on line 2 2, Fig. 1. Fig.3 is a fragmental elevation, partly in section, showing a preferred formof my invention applied to a different form of bolt. Fig. 4 is a sectionon line 4 4, Fig. 3. v

It is essential in order to produce a device of this character whichwill be adapted for use upon railway cars, for which it is especiallydesigned, that it be cheap, strong, and easily applied, and that it beornamental and artistic in its appearance. I-Ieretofore it has beendeemed necessary to provide a casing or base to serve as a support forthe working mechanism of the catch, and in applying the catch to thesash it has been necessary to mortise the sash to receive the workingparts of the catch. By my improved construction I so arrange web I) ofthe crank plate B that it serves as a base to which the handle 0 and thepin b for actuating the bolt operating rod A are secured. The revolublecrank plate is circular and is adapted to be applied upon'the outer faceof the sash or frame D and is secured in place by a single screw'G (G)passing through a centrally arranged pivot hole in the crank plate. Nomortising is necessary in fitting the crank plate to the sash, the boltoperating rod being arranged to reciprocate in a small auger hole abored from one edge of the sash to near the center of the bottom bar Dof the sash, and a small slot i)" being arranged opening from the faceof the sash into such auger hole to allow the pin 1) to engage the rod Aand by the partial rotation of the crank plate to operate to retract thebolt F (F'). By making the crank plate circular, the plate may bearranged directly against the wood work of the sash, and no matter howoften the plate is rotated no scar will be visible, sincethe plate willalways conceal any abrasion which it may cause.

H (H') indicates a spring to actuatethe catch or bolt and the crank. Thecrank operatin g and sash lifting handle 0 is so arranged with relationto the crank pin b, the sash fastener or catch F (F'), spring H (H') andthe crank pivot G (G') that when the handle 0 is swung round so that thepivot and ban- E represents the casing of the window or other opening inwhich the sash or other frame D is mounted.

In order to secure the crank firmly in place I provide a brace Iperforated at one end to receive the body of the pivot screw (G) and 7arranged to extend over the crank plate h, and provided at its other endwith a shoulder t' adapted to rest upon the sash D and also providedwith a hole passing through the shoulder to receive the brace screw J bywhich the brace is secured to the sash.

In practice the brace secured atone end by the pivot screw is set inline with the line of movement of the sash and is secured in place bythe brace screw J at the other end.

K is a washer applied above the brace at the end through which the pivotscrew passes.

This is applied to give finish to the pivot screw where an ordinaryscrew is used and it is desired to have the screw project out from theface of the crank plate; but if desired, this washer can be dispensedwith and the screw placed directly in contact with the brace.

In Figs. 1 and 2 the screw is shown with an elongated head, and a washerL is arranged between the crank plate and the head of the screw.

In practice the device is operated by grasping the handle 0 which isnormally held by the spring H or II out of avertical d rawn from thepivot G or G. The handle is then swung down into line vertical from suchpivot thus retracting the catch and withdrawing it from 4o its socket inthe frame and bringing the handle G into position to serve as a handlefor raising or lowering the sash. The sash is then raised or lowered bysuch handle and when in the desired position the handle is k freed fromthe grasp of the operator and thereupon is swung back by the catchspring into the normal position shown in Figs. 1 and 3 and the catchshoots back into its socket.

M M and N N indicate the catch sockets 5c in the casing.

Now, having described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. The combination set forth of thesash,the bolt operating rod,a revoluble crank plate adapted to be secured tothe face of the sash by means of a centrally arranged pivot, such platebeing provided on one side with the pro jecting pin arranged to engagethe bolt oper- 6o ating rod, and provided on its other side with anoutwardly projecting handle; and a centrally arranged pivot passingthrough the plate and into the sash.

2. In a sash catch the circular crank plate secured upon the face of thesash by the centrally arranged pivot, and provided upon one side withthe bolt operating pin and provided upon the other side with the handle,in combination with the brace arranged upon the outside of the crankplate and having one end secured to the pivot and the other end securedto the sash, the bolt, and the bolt operating rod.
